The integrated circuit used in this detector is uncommon today. We found it in a documentation from the 70s. Detection is done by an optical camera with LEDs and a photo sensor.
In the figure we present a circuit that has an insulation voltage of 2,500 V at 60 Hz and...
In the figure we have an audio amplifier suitable for portable applications in both mono and...
This circuit was obtained in an American documentation of the 80's and can be applied to more...
